摘要：
A lithium titanate composite material includes a lithium titanate particle and a double layered structure coated on a surface of the lithium titanate particle. The double layered structure includes a carbon layer directly disposed on the surface of the lithium titanate particle, and an AlPO4 layer disposed on an outer surface of the carbon layer. The lithium titanate composite material, as an anode active material, can be applied to a lithium ion battery to increase its electrochemical stability.
